## Discrepancy

DURING TAKEOFF ROLL OUT OF ANC, THE RIGHT ENG TORQUE INDICATIONS BEGAN FLUCTUATING.  THE PILOT ABORTED THE TAKEOFF AND RETURNED TO MAINTENANCE WITH THE AIRCRAFT.  MAINTENANCE PERFORMED A GROUND RUNUP CHECK AND ISOLATED THE PROBLEM TO THE RIGHT FUEL CONTROL UNIT.  THE RIGHT FUEL CONTROL WAS REMOVED AND REPLACED WITH A SERVICEABLE FUEL CONTROL UNIT.  GROUND RUNS WERE ACCOMPLISHED AND ALL ENGINE PARAMETERS OPERATED NORMALLY.  THE AIRCRAFT WAS RELEASED FROM SERVICE.  (M)
